Strength design of stainless steel joint

Stainless steel pipe fitting is the most important large load bearing member on the support.Strength design of stainless steel joint

The design and optimization of Eaton transition joint of stainless steel pipe fitting, preparation technology of stainless steel pipe fitting, theoretical design and experimental analysis of axial compression property were studied.

Strength design has always been a difficult and hot point in the structural design of stainless steel pipe fittings.

The axial compression strength of the stainless steel fittings in ningbo can be significantly improved with the appropriate content of ring layer in the stainless steel clamp joint, whether it is the angle-ply stainless steel fittings or the axial/annular orthogonal ply stainless steel fittings.After changing the 20% Angle layering (axial layering) to annular layering, the axial compression strength of the stainless steel pipe fittings with winding Angle of 20° was about doubled, and the axial compression strength of the orthogonal layering stainless steel pipe fittings was also increased by more than 10%.

The finite element model was used to analyze the bearing performance of the composite material thrust support on the reusable launch vehicle verifier x-33 and Atlas V launch vehicle.

It is pointed out that the comprehensive bearing capacity of x-33 thrust support structure is good.

It is suitable for more complex load strip Eaton hydraulic fittings, while Atlas v-type thrust bracket structure has a better compression bearing capacity. Anhui stainless steel pneumatic pipe fittings are suitable for loading conditions dominated by large thrust.

The service life of stainless steel pipe fittings has a lot of influence factors: let's take a look at the following different processing process method, processing elbow, when tapping to the thread in accordance with the size, it may be two taps eton card type joint end face collision, the reason is the tap base surface is longer. 

In this case, it is necessary to shorten the end face of the tap, but it may adversely affect the function of tap.It can be seen from the relation between the front and back taps and the workpiece being processed when the end face is shorted that the thread part of the tap after the end face is shorted cannot be normally introduced into the hole, but is pressed into the hole by the end face, thus affecting the function of the tap.

In the mill, stainless steel stamping elbow pipe fittings on the whole length of the thermal mechanical historical changes obviously, especially in micro stamping stainless steel elbow pipe fittings produced, will strongly affect the finishing mill on the degree of recrystallization and grain growth and precipitation, and causes the entire stainless steel stamping elbow pipe length on the final microstructure and function of the radical changes.The original geometric shape of the front guide must be maintained when grinding.It is a good way to solve the long base surface of the tap is to customize the short base surface of the tap according to the specific requirements of the thread being processed.

In order to solve these problems, some users have to repair the front guide part of the tap, and repair the front guide part of the tap before and after grinding.Due to the shape change of the front guide after grinding, the function of tap will still be affected.The solution to this problem is the furnace rolling mill: the furnace rolling mill consists of a reciprocating roughing mill and a 4-high reciprocating finishing mill.Two hot rolling mills are installed on the conveying lines on both sides of the finishing mill.The output roll way usually consists of a laminar cooling system and a take-up station.
